Topic: [0Th]Ozcoin Pooled Mining |DGM 1%|Stratum+VarDiff port 80|NEW CN mining| - page 85. (Read 398185 times)

I think the confusion lies in the fact that OzCoin shows the found block was worth 157 BTC while the pool only paid out 47 BTC, so the questions is then where did the 110 BTC go ?

As you describe DGM; a share that is being submitted at time T is scored compared to the other shares based on the value of the transaction that is submitted to the network at time T, even if the pool does not find the block that transaction is included in. If someone includes a transaction fee of 100.000 BTC, each share submitted at that time would have an abnormally high score value whether or not OzCoin finds the block.

Seeing as this score is only to determine how much of the total generated BTC a share is worth to a miner compared to other shares submitted by miners, the question remains if the transaction fee received by OzCoin is 10.000 BTC then 10.000 BTC + blockreward should be divided amongst all all the shares submitted within the scoring period.

As I started out saying, now it looks like OzCoin received 157 BTC and only paid out 47 BTC. Regardless of any reward system, the payout on each share should have been roughly 3 times at high as it usually is (with DGM less so than with PPS, but higher over a longer period of submitted shares).

This is how I see it at least

Sorry for the slow reply, was a bit sick yesterday and crashed out once I got kids to bed, then slept for 13hours.

I will try to explain (excuse me if I state some obvious stuff we all should know)
transactions get included in blocks, some have a txn fee  
each longpoll (someone finding a block on the network) some transactions are included into the block that triggered the longpoll,
so the memorypool of txns changes, longpoll signifies  a change of data to be hashed by miners.
The way DGM works is each share is scored at the time it was submitted (like "if a block was found now")
So at different times the value of the submitted share changes depending on the value of the txn fees we are currently hashing into a block.
Over time this should even out - unless ppl keep wasting BTC like they did in block 201731 - I can not stress enough how unusual the txn fees in this block were.

This means if Ozcoin had not found the block with unusually high txn fees we still would have paid a portion of the shares at that rate "as if we were finding the block now" to our miners.

Including TXN fees in blocks was 1st discussed in the DGM thread here
https://bitcointalksearch.org/topic/m.573288
Ozcoin has always strived to have the correct implementation of DGM.
Being the only DGM pool paying out TXN fees you are still ahead of the other DGM pools which ever way txn fee is calculated
If there wasn't a mistake by someone that had put those fees in that block or if another pool had found the block we wouldn't even be having this discussion

Hope that helps clarify

EDIT: we are planning to make an extra payout for that round, strictly following DGM we would not. BUT as this is a very unusual situation I propose to make another payout to miners of approximately 1/2 of the bonus txns and put the other 1/2 aside for a rainy day (bad luck streak).

I read the exchange and it sounds like the pool calculates share value and tx fee portion to credit to my account before a block which that share is applied to is even found.  That makes no sense.  So if you could re-explain it in more laymen terms I'd appreciate it.

Ok
Talked to roomservice - I felt a copy/paste would be better than me trying to re-explain it

the problem is that people don't understand how tx fee payout on dgm work
quote meni:
The correct way is much simpler, it's to use the block reward of the share itself. That is, the share is a hash of a block header you hand out for the getwork, which has a merkle root of a transaction list with a given total transaction fee, which together with generation is the total block reward. That's the value of B which should be used for this share.

did you get it?
let me explain in easy words
ahh yes
if you submit a share right now
we caculate the actual share reward at the time
you will be credited for block reward + tx fee if a block is found now
but total block reward may be different
what pool finds is another story yes
ahh
it could be possible that the pool didn't find this 150btc block
and would have credited tx fees nevertheless
yep
we even credit tx fees right now
even if we don't find the next block
yes
so in this case you were really lucky
can I quote this conversation?
heh yeah
sure
people who submitted shares a few minutes before we found this block should see a really nice increase of score
but it won't be a REALLY big difference - i guess most people don't even realize it

So we calculate the value of the share +txn fee at the time it is submitted not after the block is found.  Which looks to be fine if there is not much variation in txn fees. On this occasion with an extremely high (unusual ) reward I feel this has not worked out the way it was intended.

It is late, will PM meni and sleep on it I think
best wishes

misreading I think


I was already waiting for one of the staff to appear to check that everything went as it should, I believe it has. If we find any discrepancies there will be an extra payment.
If not, no

So there will be another payment coming to however is entitled to it ? Or am I misreading it ?

I think that table works off pool_B not pool_B +txn fees - need to look into that
currently pool fee is taken before txn fees are added in as well - this will change come reward halving.

Question: If the block was 154 BTC, why did the pool only pay out 47?

 

someone/thing screwed up

to clarify
those 3 txn, one is for 3.xx btc with a 9.xx btc fee, a 21.xx btc txn with a 21.xx fee and another txn with a 64BTC fee

How in the world do transaction fees get that high?

Very nice indeed  

just noticed this in the wallet - been out a bit today

Good thing for our miners Ozcoin is one of the few pools that pay out txn fees

Yes indeed spendbitcoins.com is great (Graet) for Aus people
You can even do a bpay to your credit card ...

Bitcoin: Makes paying taxes more FUN !!!

With the help of spendbitcoins.com I have just paid Ozcoin's company "Annual Review Fee" in Bitcoins
$230AUD for those interested.

I think thats really cool - hope others agree
Cheers
